For an optimal water balance, pH Expert includes a function allowing to adapt the injection cycles according to the alkalinity of the water (TAC).

It is thus possible to choose 3 settings: Low alkalinity (TAC less than 10°f), Standard alkalinity (default setting), High alkalinity (TAC greater than 15°f)

Depending on the value measured by their probe, Zodiac pH regulators automatically adjust the pool's pH up or down, thanks to their peristaltic metering pump.

The dosing time depends on the difference between the pH of the pool and the ideal pH (set point). The water balance is thus maintained at the desired value without any intervention.

Zodiac pH regulators are equipped with an exclusive overdose safety device to prevent any excessive injection. This security is adjustable.

For the best comfort of bathers, the pH of the pool must be maintained between 7.0 and 7.4

Below (acid pH) the water is aggressive and above (basic pH) there is a risk of algae development and over-consumption of disinfectants)

The ideal pH of pool water corresponds to the average pH of the human body, and more particularly of the blood, it is between 7.35 and 7.45
